Research Interests

The overall aim my research is to understand the evolution of insect chemical communication. My lab integrates genetics, behavioral analysis, and mass spectrometry to detect and characterize the chemical and functional diversity of lipid pheromones in Drosophila and other insects. My major interests are as follow:

1. Biodiversity of pheromones: characterizing the chemical diversity, function, and biochemical production of lipid pheromones amongst Drosophila species, including native Hawaiian Drosophila
2. Neural basis of pheromone detection: elucidation of the cellular and molecular mechanisms underlying pheromone detection and behavior
3. Methods for lipid pheromone analysis: development of improved mass spectrometry-based methods for lipid structural characterization and detection of pheromones from intact insects
